TURBOCOMPRESSOR Russian patent published in 2014 - IPC F01D25/18 F02C6/12 F02B39/14 

FIELD: machine building.

SUBSTANCE: turbocompressor comprises a turbocompressor casing, a casing of bearings with oil supply channels, a rotor with bearings being set on its shaft, an oil drain cavity, an oil drain tube. A rotating knee piece with a bolt of the rotating knee piece is installed in the turbocompressor casing. The axial bore of the bolt is connected to the oil drain cavity. The output of the rotating knee piece is connected to the engine case via a drain tube.

EFFECT: improved reliability of a turbocompressor due to the elimination of back pressure of tramp oil in an oil drain tube thus such operational defect as oil entrainment is prevented and turbocompressor cooling is improved due to the increased oil consumption.
